CVE-2025-67990 is a reflected Cross-site Scripting (XSS) vulnerability identified in the RealMag777 GMap Targeting plugin, affecting versions up to and including 1.1.7. The root cause is improper neutralization of input during web page generation, which allows an attacker to inject malicious JavaScript code into web pages viewed by other users. This vulnerability is classified as reflected XSS, meaning the malicious payload is embedded in a link or request and reflected back in the server's response without proper sanitization. When a victim clicks a crafted URL or interacts with a manipulated input, the injected script executes in their browser context. This can lead to session hijacking, theft of sensitive information such as cookies or credentials, defacement, or redirection to malicious sites. The plugin is used to provide geolocation and map targeting features, commonly integrated into websites for marketing or user experience enhancements. No CVSS score has been assigned yet, and no patches or official fixes have been released as of the publication date. The vulnerability was reserved in December 2025 and published in February 2026. Although no known exploits are reported in the wild, the vulnerability's nature and ease of exploitation make it a significant risk. The lack of authentication requirements and the reflected nature of the XSS increase the attack surface, as any user clicking a malicious link can be targeted. The vulnerability affects all installations using the vulnerable versions of the plugin, which is likely deployed on WordPress or similar CMS platforms. The absence of CWE identifiers limits detailed classification, but the issue clearly falls under CWE-79 (Improper Neutralization of Input During Web Page Generation).

The primary impact of CVE-2025-67990 is on the confidentiality and integrity of user data and sessions. Successful exploitation allows attackers to execute arbitrary scripts in the context of the victim's browser, potentially stealing session cookies, login credentials, or other sensitive information. This can lead to account takeover, unauthorized actions on the victim's behalf, and further compromise of the affected web application or user accounts. Additionally, attackers may use the vulnerability to deliver malware, perform phishing attacks, or deface websites. The availability impact is generally low but could be indirectly affected if attackers disrupt user trust or cause operational issues. Organizations relying on the GMap Targeting plugin for critical marketing or geolocation services may face reputational damage and operational disruptions. Since the vulnerability is reflected XSS, it requires user interaction (clicking a malicious link), but no authentication is needed, broadening the potential victim pool. The lack of patches increases exposure time, raising the risk of exploitation once public proof-of-concept code or exploits emerge. Overall, the threat poses a significant risk to organizations using the affected plugin, especially those with high user traffic or sensitive user data.

1. Immediate mitigation should include implementing strict input validation and output encoding on all user-supplied data, particularly those reflected in web pages by the GMap Targeting plugin. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 3. Monitor and filter incoming requests for suspicious payloads that may attempt to exploit the reflected XSS. 4. Disable or remove the GMap Targeting plugin if it is not essential to reduce the attack surface until a patch is available. 5. Keep all CMS platforms and plugins updated and subscribe to vendor security advisories for timely patch releases. 6. Educate users and administrators about the risks of clicking untrusted links, especially those related to the affected web applications. 7. Use web application firewalls (WAFs) with rules specifically designed to detect and block reflected XSS attempts targeting known vulnerable parameters of the plugin. 8. Conduct regular security assessments and penetration testing focused on input handling and output encoding to identify similar vulnerabilities proactively. 9. Once a patch is released, prioritize immediate deployment and verify the fix through testing. 10. Implement multi-factor authentication (MFA) to reduce the impact of credential theft resulting from XSS exploitation.
